Wow, you have your hands full there my friend. I want a bigger space and more tents but I get overwhelmed a bit at times with my small op. That's really just in my head and me being overly critical & overthinkin about things.
Now when I see your pics of the plants and thinking you have a huge space I know whats up. Very cool, I could just see me tripping over the ducting and crash & burn the whole thang lol.
Why sure you can fit the 2.1 in there, I think that's what you said...with a bit of pork slogoffottery er something...Cheers man
I'm headed over to Insta to check the other.
